do you think this will work. i want to build an additional sump like system that will have a DBS, Refugium and a draw with liverock in.I’m going to use those plastic storage draws you get at most retailers.i will turn one draw upside down and install a light in for the rfugium.the last draw will have a pump or maybe some one will have an idea on how i can return the water to my sump without a pump

I see a small problem with this. if you use the cheap draws they sell at Jet stores etc. you should remember that they are not very strong and probably would eventually buckle under the weight of the water inside.. I can estimate that each draw will wait about 50kg and from your drawing I estimate you'll have at least 200 killos of water. way too heavy. also how are you gonna open the draws to clean with the water inside .. as soon as you open the draw more than half way the center of weight will shift to the outside and you gonna have 50 liters of water on your carpet. or maybe I'm wrong but it just seems that way

I have better use for VODKA...

Whoever said anything was possible
obviously never tried slamming a
